Read the following passage about the CULTURAL DIVERSITY and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.
[I] Belgium features a fascinating mix of ancient traditions and contemporary legislation, showcasing the country’s rich history. [II]. In Belgium, the families of the bride and groom each pitch in by providing a sheet of paper for the wedding invitations, in line with a long-standing tradition. [III] The wedding invitations symbolize the new partnership and the merging of the two families. [IV]
In an old Belgian tradition meant to bring the two families closer together, the bride would pause halfway down the aisle to give her mother a solitary flower. They hold each other's arms. The newlyweds then make their way to the groom's mother-in-law during the recessional, where the bride presents her with a solitary flower as a token of her affection. As a sign of the bride's acceptance of her new mother, they embrace.
Carrying a uniquely embroidered handkerchief bearing the bride's name is one of the most significant and long-standing customs of the Belgian wedding. This handkerchief will be framed and displayed in a special spot after the wedding. Before each subsequent female member of the bride's family is married, the handkerchief is taken out of its frame, embroidered with the name of the new bride, and then passed down through the generations. A bridal handkerchief is a treasured memento that is passed down through the generations.
There are two big chairs placed near the altar where the bride and groom sit during the wedding mass, representing their throne as king and queen for the day and the location. As the ceremony comes to a close, the groom places the wedding ring on the third finger of the bride's left hand. Because it is a circle, the ring represents love that knows no bounds, and the third finger of the left hand represents love because it is thought to hold the vein that goes to the heart. Soon after the wedding, the newlyweds kiss for the first time as husband and wife. Because each partner takes a breath of their new spouse's spirit, the kiss is a metaphor for the couple's spiritual union.
Traditionally, as the bride and husband leave the church, the bridesmaids gather a handful of pennies and then scatter them among the less fortunate outside. The happy couple might increase their chances of financial success by donating to charity.
A honeymoon is for the newlyweds after the wedding. Honey wine, or mead, was traditionally drunk during the 28-day honeymoon, which corresponds to one lunar cycle, in ancient times. The purpose of this was to prevent the bride's relatives from attempting to reclaim their daughter from her husband.

Read the following passage about Innovation Driven by Environmental Need and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.
Green startups have emerged as forces for positive environmental change. These companies create sustainable solutions for urgent ecological challenges. Unlike traditional businesses prioritizing profits, green startups balance financial goals with environmental responsibility. Many were founded by young entrepreneurs who witnessed environmental degradation and felt compelled to act. Their mission extends beyond making money; they aim to heal our planet while building successful businesses.
Eco-friendly startups have grown across various sectors. From renewable energy and sustainable agriculture to zero-waste products, these companies revolutionize how we interact with our environment. GreenWave developed ocean farming requiring no fertilizers while capturing carbon. Notpla created edible packaging from seaweed as a plastic alternative. These innovations show how creativity and environmental consciousness produce extraordinary results. Their success proves sustainability and profitability can coexist.
Funding for green startups has increased in the past decade. Investors recognize supporting environmentally responsible businesses is both ethical and financially prudent. Venture capitalists have established funds dedicated to sustainable startups, providing capital to scale operations. Government grants have become more accessible to entrepreneurs developing green technologies. Despite positive developments, green startups still face regulatory hurdles and competition from established industries resistant to change.
The future looks promising for environmental businesses as consumers shift toward sustainable products. Studies show modern consumers, particularly younger generations, will pay premium prices for eco-friendly alternatives. This trend creates fertile ground for green startups to thrive. As climate concerns intensify, demand for innovative environmental solutions will grow stronger. Green startups are positioned to meet this demand while driving positive change, demonstrating business innovation and environmental stewardship can create a sustainable world.

Read the following passage about urban shift and mark the letter A, B, C, D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.
[I] Sperm whales are fascinating creatures. [II] They possess the biggest brain of any species, six times larger than a human’s, which scientists believe may have evolved to support intelligent, rational behavior. [III] They’re also highly social and capable of making decisions as a group. [IV] But there’s also a lot we don’t know about them, including what they may be saying to one another when communicating with a system of short clicks, known as codas.
Now, new research published in Nature Communications today suggests that sperm whales’ communication is actually much more expressive and complicated than was previously thought. A team of researchers led by Pratyusha Sharma at MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) working with Project CETI, a nonprofit focused on using AI to understand whales, used statistical models to analyze whale codas and managed to identify a structure to their language that’s similar to features of human language. Their findings represent a tool future researchers could use to decipher not just the structure but the actual meaning of whale sounds.
For the study, the researchers examined recordings of 8,719 codas from around 60 whales collected by the Dominica Sperm Whale Project between 2005 and 2018, using a mix of AI algorithms for pattern recognition and classification. The AI then turned the clicks within the coda data into a new kind of data visualization called an exchange plot, revealing that some codas featured extra clicks. These extra clicks, combined with variations in the duration of their calls, appeared in interactions between multiple whales, which they say suggests that codas can carry more information and possess a more complicated internal structure than we had previously believed.
The team’s next step is to build language models of whale calls and to examine how those calls relate to different behaviors. They also plan to work on a more universal system that could be used across species, says Sharma. Taking a communication system we know nothing about, working out how it encodes and transmits information, and slowly beginning to understand what’s being communicated could have many purposes beyond whales. “I think we’re just starting to understand some of these things,” she says. “We’re very much at the beginning, but we are slowly making our way through.”
